Automotive steering bulb long in service life

Abstract

The invention discloses an automotive steering bulb long in service life. The automotive steering bulb long in service life comprises a bulb seat and a bulb pin, wherein the bulb pin is arranged in the middle of the bulb seat; the bulb pin is in clearance fit to the bulb seat; the bulb pin is rotatably connected to the bulb seat; the bulb seat comprises a shell and a bottom plate; the bottom plateis arranged at the lower end of the shell; the bottom plate is U-shaped; the bottom plate is fixedly connected to the shell in a locking manner; a supporting plate is arranged in the upper side of the bottom plate; a shock absorbing device is arranged between the bottom plate and the supporting plate; the bottom of the bulb pin is located above the supporting plate; the bulb pin comprises a bulband a connecting rod; the bulb and the connecting rod are integrally formed; a first groove is formed in the middle of the connecting rod; a mounting hole is formed in the upper end of the connectingrod; a bush is also connected to the outer side above the bulb in a sleeving manner; and the bush is rotatably connected to the bulb and the shell, separately. The automotive steering bulb is simple in structure, various in function, high in safety protective performance, good in sealing property and long in service life, and is popularized favorably.

Description

technical field [0001] The invention relates to the technical field of automobile steering ball joints, in particular to an automobile steering ball joint with long service life. Background technique [0002] With the gradual improvement of people's living standards, cars have become more and more popular, and the comfort and stability of cars have become the current trend of car development. The steering ball joint is one of the key components of the vehicle steering mechanism. The vehicle steering ball joint provides multi-angle rotation when the car is turning, so that the steering mechanism can turn smoothly, achieving the purpose of reducing vibration and smooth steering. [0003] In the steering ball head of the prior art, after the ball head is used for a long time, the inner ball head will be worn, which will cause the rotation of the ball head to be affected, and the friction force will become larger, resulting in poor use effect and affecting the use effect. At the...

Problems solved by technology

[0003] In the steering ball head of the prior art, after the ball head is used for a long time, the inner ball head will be worn, which will cause the rotation of the ball head to be affected, and the friction force will become larger, resulting in poor use effect and affecting the use effect. At the same time, In the prior art, in order to prevent the dust jacket from falling off from the cylindrical section, it is often necessary to set a support ring inside the dust jacket as a skeleton support, resulting in prolonged assembly hours and reduced production efficiency. At the same time, the dust jacket after assembly is also sealed. Disadvantages of poor effect
